IGN has another look at Pirates of the Burning Sea posted, and it's got lots of interesting information about the land and naval combat.

We got a brief tour of the game, showing off a few towns, land combat, and naval warfare. Like most other MMOs, things start off on a character select screen where your nationality. Instead of the British, French or Spanish, we went with the Pirate affiliation because, well, we like pirates. Next up is a character customization screen, where we cycled through a few silly hats and coats, selected colors, facial appearance, eventually settling on a distinguished-looking clothing combination.
